Although the resemblance between LCCFIO and the aforementioned La\(_{2-x}\) Sr\(_x\) CoIrO\(_6\)  and La\(_2\) ZnIrO\(_6\)  compounds suggests that the most plausible scenario is the one with two AFM sublattices at Co/Fe and Ir sites [1]}, [2]}, [3]}, one must not take precipitate conclusions since a thorough XMCD study of several distinct combinations of Ir and 3\(d\)  TM ions in DP compounds showed that the magnetic ground state of these Ir-based DPs is susceptible to the structural and electronic environment [4]}. Our magnetization data are not enough to unambiguously determine whether the FIM behavior observed in LCCFIO is due to the AFM coupling between the Co/Fe and Ir FM sublattices or NCM from two interpenetration AFM sublattices for Co/Fe and Ir. For this last scenario, the FIM behavior would result from uncompensated Co–Fe AFM coupling or spin canting. Specific measurements such as temperature-dependent XRD, XMCD, and NPD would be necessary to unravel the magnetic structure of LCCFIO.
